我已经设置我的网页几个星期了。就在今天，我决定将我的导航栏部分、元标记和链接放在母版页上。当我这样做时，除了一件事之外，一切都很顺利。顶部信息部分背景在底部被截短。这几乎就像它没有读取我的样式表中的 height: 100% 一样。这是我的母版页，我将一些内容移到了其中。

@renderSection("scripts",false)

这是我的顶级信息部分，背景被截断
<section class="topInfo">
<div class="container">
<div class="row">
<div class="col-md-10 col-md-offset-1">
<h1 class="topInfoText text-center">Aerial Drone Services, Stock Footage, and Affordable Prints</h1>
</div>
<div class="col-sm-4 col-sm-offset-4">
<a class="btn bannerBtn btn-block" href="#">Learn More</a>
</div>
</div>
</div>
</section>
以及 topInfo 类的样式
.topInfo {
background-image: linear-gradient( rgba(0,0,0,.25), rgba(0,0,0,.25) ), url('/CMS_Static/Uploads/313864614C6F6F/exuma rocks 2.jpg');
background-attachment: fixed;
background-size: cover;
background-repeat: no-repeat;
background-position: center;
height: 100%;
}
最佳答案
具有 height: 100% 的元素只能与其父元素一样高。 parent 多高？如果它是 body 的直接子项，请尝试在您的 CSS 中进行设置:
html, body {
height: 100%;
}
